A new residential build is in progress for a detached garage with upstairs bonus area. 200A is dedicated to the building off an 800A meter. There will be multiple EV chargers, tankless hot water heater, upper and lower HVAC, etc., and now that there's a desire for a bit more devices, a sub-panel should go in.
After the roof was constructed, it became clear there's quite a bit of space upstairs where the breaker panels will be (full-standard stairs), so a bathroom is being planned right where the main line comes in. Of course the breaker panels can't be in the bathroom, so the plan is to extend the unfinished equipment room into the space where the bathroom would be to encompass the breakers would be (city code hotline to confirmed they don't see an issue with an equipment room through the bathroom). The original plan was to have the breakers on the horizontal lower wall in the attached image, but doing so would mean losing 6" of precious bathroom width since 36" of course needs to be clear in front of the panels (with the door closed).
Now the thought is the breakers can be on the wall where they are shown (main line has been run and there's enough room to move the panel slightly). A sub-panel could go anywhere in compliance, but there is a slanted roof, and the yellow area is the <6' zone for height with 8' 4.5" at the apex. As such, the equipment room that has more wall space is simply not tall enough for a panel.
So, per NEC 110.26(A)(2), I believe we could put the main and sub panel side with a 2x4 in the middle where shown and be in compliance (clear area 30" W, >36" D, ~8' H). The 30" width I understand is not 15" from center on each side. I thought I'd see if you see an issue with or have other ideas how to accomplish this and take up as little space as possible while being safe and compliant.
Thanks!
